LINE-WIRE FASTENER.

Specification of Letters Patent.

Patented June 23, 1914.

Application filed September 13, 1913. Serial No. 789,687.

To all whom it may concern:

Be it known that I, THOMAS A. WISEMAN, a citizen of the United States,residing at WVinchester, in the county of Franklin and State ofTennessee, have invented certain new and useful Improvements inLine-Wire Fasteners, of which the following is a specification,reference being had to the accompanying drawings.

This invention relates to new and useful improvements in line wirefasteners, and the primary object of the invention is to provide adevice of this character provided with means for quickly and readilyattaching telephone, telegraph, and similar wires to a post.

A further object of the invention resides in providing a pair ofclamping members with improved means for securing the same to the postand designed for securely engaging the line wire.

A still further object resides in providing a device which is simple anddurable in construction, inexpensive to manufacture, and one which isvery efficient and useful in operation.

\Vith these and other objects in View, my invention consists in thenovel features of construction, combination and arrangement of parts aswill be hereinafter referred to and more particularly set forth in thespecification and claims.

In the accompanying drawing forming part of this application, Figure 1is a plan view of my device applied to use, showing the insulator cap insection. Fig. 2 is a side elevation thereof. Fig. 3 is a side elevationof one arm of the clamping member removed. Fig. 4 is a horizontalsection as seen on the line 4L4 of Fig. 2. Fig. 5 is an end elevation ofoneof the clamping members.

In describing the invention, I shall refer to the drawing in whichsimilar reference characters designate corresponding parts throughoutthe several views and in which- 1 indicates an insulator cap or the likeap plied to a post or other object, and to which a line wire 2 isadapted to be secured. In order to secure said line wire to theinsulator cap, I provide my improved device which consists first of apair of arcuately designed wire clamps or the like 3 which are adaptedto encircle said cap 1 in a groove 4: of the latter, the ends of saidwire members 3 being spaced from one another and arranged parallel whenthe same are so mounted on the cap. I also provide a pair of clampingmembers A and B, each of which comprises a pair of arms 5 and 6, thearms 5 being provided with a plurality of openings 7 therein throughwhich the parallel portions of the wire members 3 are disposed. Throughthis medium the clamping members A and B are secured to the cap 1 andsaid clamping wires 3 tightly clamped about said cap.

The arm 5 of each of the clamping members A and B has a downwardlyinclined projection 8 formed on the inner end thereof, which projectionis slotted, as shown at 9, and the upper edge of the projection is cutaway or offset to form a notch 10. The arm 6. on the other hand, of eachof the clamping members, is also provided with a depending projection 11which is designed to form a central tongue adapted for reception in theslotted portion 9 of the projection 8 on said arm 5. A pin or bolt 12passing through the arms of the projection 8 of the one member and thepro j ection ll of the other member pivotally retains said arms 5 and 6together, and the inner edge of the projection 11 is cut away or offsetto form a notch 13 which is complementary to the notch 10 in the othermember. These notches l0 and 13 are adapted to be brought together whenthe arms 5 and 6 are brought in clamping relation to one another and theopening so formed between the notches is adapted to receive the linewire therethrough. In order to limit the swinging movement of the onearm with respect to the other, the projection 11 on the arm 6 is offsetadjacent its lower end to form a shoulder 14 which is adapted forengagement with the under face of the arm 5 when said arm 6 is swung toits open position. This shoulder obviously limits the movement of thearm 6 with respect to the il-I'lTl 4 A loop or the like 15 is pivotallyengaged adjacent the outer end of the arm 5 and is adapted to receivethereunder the outer end of the arm 6 to retain said arms 5 and 6 inclamping relation to one another, and in order to permit the arm 6 to bereadily received under said loop, the upper face of said arm 6 at itsouter end, is beveled, as shown at 16. A spring member 17 is arranged inconnection with said loop 15 to normally retain the latter in itseffective or raised position so that when once disposed to its eifectiveposition, said loop is not adapted to be readily removed through casualdisplacement.

It will be seen from the above description of the operation of thedevice that after the clamping members A and B have been properlyapplied to the insulator head, a line wire may be quickly and readilyclamped between the arms of said members A and B to be securely butremovably held to said insulator cap. It will of course, be understoodthat the line wire is held between the complementary notches 10 and 13on the arms of the clamping members and the manner of applying thedevice to use will be readily understood from the above description ofthe operation of the device.

It will be seen from the above that I have provided a device which issimple and durable in construction, inexpensive to manufacture and onewhich will be very eflicient and useful in operation and, while I havedescribed the elements best adapted to perform the functions set forth,it is obvious that various changes in the form, proportion and in theminor details of construction may be resorted to, within the scope ofthe appended claims, without departing from the spirit or sacrificingany of the principles of the invention.

Having thus described my invention, what I claim, is:

l. A line wire fastener comprising a pair of clamping members, eachcomposed of a pair of arms pivoted one to the other, said arms beingprovided with complementary notches to receive a wire therethrough,means to limit the swinging movement of the arms with respect to oneanother and means to clamp said arms together, and wire membersconnecting said clamping members.

2. A line wire fastener comprising a pair of clamping members, eachcomposed of a pair of arms pivoted one to the other, said arms beingprovided With complementary notches adjacent their pivotal points to receive a wire therethrough, means for limiting the swinging movement ofthe arms and the clamping members with respect to one another, springheld pivotal means for clamping said arms together, and wire membersconnecting said clamping members, said connecting means affording ameans for securing the clamping members to an object.

3. In a line wire fastener, a clamping member consisting of a pair ofarms, each of which is provided with a depending projection at one endthereof, the projection of one arm being slotted and the projection ofthe other arm being reduced in thickness and adapted to be received inthe slotted portion of the other arm, means engaged with the projectionsof said arms to pivotally secure the latter together, said projectionsbeing provided with complementary notches adapted to receive a line wiretherethrough, means in connection with the pro jection on the lastmentioned arm adapted to engage portions of the first mentioned armwhereby to limit the pivotal movement of said arms with respect to oneanother, and means for clamping said arms together.

4- In a line wire fastener, a clamping member comprising a pair of arms,each of which is provided with a depending projection at one endthereof, the projection of one arm being slotted and the projection ofthe other arm being reduced in thickness to form a tongue adapted to bereceived in the slotted portion of the other arm, means engaged with thedepending portions of said arms to pivotally connect the same together,said projections being provided with complementary notches adapted toreceive a line wire therethrough, the projection of the last mentionedarm being offset to provide a shoulder adapted for engagement with theunder face of the first mentioned arm to limit the movement of said armswith respect to one another, and a pivoted loop car ried on the firstmentioned arm adapted to engage the. outer end of the second mentionedarm to clamp said arms together.

In testimony whereof I hereunto aflix my signature in the presence oftwo witnesses.
